SELF-LUBRICATING SPRING HANGER, BOLT, AND EYE.

Application filed May '7, 1921. Serial No. 467,704.

To all whom t may concern.'

Be it known that I, ARZENO J. DILLEY, residing at River Forest,Michigan, a citizen of the United States, have invented certain new anduseful Improvements in Self-Lubricating Spring Hangers, Bolts, and Eyes,of which the following is a specification.

My invention relates to an improvement in a self-lubricating springhanger, bolt and eye, and it comprises the eye of a spring, with abushing and washers or mats at the ends thereof of absorbent material,hangers, and a bolt for holding the parts together.

In the accompanyiiig drawings z- Fig. l is a view in perspective of theend of a spring holding the eye having the bushing therein, and showingone of the ab sorbent mats or washers;

Fig. 2 is a view of the bushing;

F'g. 3 shows the spring-bolt and hanger partly assembled;

Fig. 4 is a side view of one of the hangers; and

Fig. 5 is an inside view of the nut.

The numerals l, 1, represent the usual leaves for forming the spring;and 2 is the usual eye formed by ceiling the end of the spring intocylindrical form, one being provide-d, of course, at each end of thespring.

TVithin this eye a metal bushing 3 is fitted. This is made of bronze, orother material, and preferably a trifle less in length than the lengthof the eye. In the space 1n the eye at the ends of the bushing, theabsorbent mats or washers 4 of felt or other material are inserted. Oilduct-s l2 (las shown in full and in dotted lines in Fig. 2) arepreferably formed in th-e ends of the bolt 6, and may be used as a meansfor conducting lubricant to the absorbent mats or washers 4, if desired.

These washered ends of the eye are einbraced by the two hangers 5, 5;and spring bolt 6, having a semi-spherical head `7 and held by asemi-spherical nut 8, is inserted through the orifices 9 in the hangers,the washers, and the bore of the bushinggan'd the nut 8, which may be alock-nut, is screwed on the end of the bolt. The bolt 6 itself may beground to facilitate the distribution of the oil, for example asindicate-d bv the groove 13 extending spirally around its surface asviewed in Fig. 2. The head of the bolt may be of various shapes,

as may the form of the nut, although the semispherical form ispreferred. A lubricant hole 10 is provided on the upper surface of theeye to receive the oil. The surfac-e of the metal bushing 3 is providedwith grooves 11 to receive and distribute the lubricant from the hole l0formed in the springeye.

In this way, it is possible to entire-ly do away with the usual oil orgrease-cups, and thus eect a very material saving in the cost ofconstruction and the maintenance of a car; and with this construction, Ihave found by actual demonstration that each eye will hold enough oil tolubricate the spring bolt, eye and hanger in a travel of at least fivethousand miles without re-oiling.

The absorbent washers not only lubricate the hangers and the end of theeye, but also hold a large portion of the oil within the bushing and eyeand in contact with the body of the bolt, and at the same time keep outdust and grit. Altogether the parts thus formed and assembled provide aneffectual lubricating joint, and one which is simple, inexpensive, andeasy to keep in order and lubricated.

I claim:

1. A selflubricating spring hanger, bolt and eye including a leaf-springhaving an eye formed at one end thereof, means of support for said eye,a bolt extending through the eye for fastening said means thereto, abushing through which the bolt extends and having an external groove forreceiving and distributing lubricant, and the eye having a hole forlubricant leading to the external groove in the bushing.

2. A self-lubricating spring-hanger, bolt and eye including aleaf-spring having an eye formed at the ends, hangers embracing the endsof the eye, a spring-bolt externally grooved and having oil ductsextending in from the'ends, abushing through which the bolt extends andof less length than the eye while tting the space between the bolt andeye, said bushing having an external groove for receiving anddistributing lubricant, the eye having a hole forv lubricant leading tothe external groove in the bushing, and absorbent material occupying thespaces between the ends of the bushing and the hanger adapted tofacilitate the distribution of lubricant and also exclude extraneousmaterial. i
